Consider the following premises :
People don't want to be killed, especially when they did nothing wrong. People also don't want to be hurt, especially when they did nothing wrong.
Therefore violence should be minimized as much as possible.
If you are in a desert have a bottle of water & a mugger attacks you & steal the water, they will have to compensate you (sooner or later), regardless of their circumstances.
If some people break your front door steal some food & run away, they will have to compensate you (sooner or later), regardless of their circumstances.
You are not forced to make a compensation claim.
Do you agree ?
You think that some people (companies) have illegitimate property claims, because It was financed with stolen money/items/scams...etc . Maybe & we'll have to see on a case by case basis, It's not imcompatible with voluntaryism.
What's the problem with voluntaryism and why is it so bad ?
